DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

Generally, this disclosure discloses various technologies for reducing complexity and cost of vehicle manufacturing, without negatively affecting vehicle reliability and serviceability. This is accomplished through inclusion of manifolds in vehicles, whether completely or partially, in place of individual hoses or pipes, in order to transfer fluids between separate vehicular components. Instead, for example, the separate vehicular components are hard mounted to a manifold for a vehicular assembly, such as during vehicle manufacturing, where the manifold can facilitate various fluid conduction processes for various vehicular purposes, such as internal environmental comfort, heating or cooling of a powertrain, or others.

Various terminology used herein can imply direct or indirect, full or partial, temporary or permanent, action or inaction. For example, when an element is referred to as being “on,” “connected” or “coupled” to another element, then the element can be directly on, connected or coupled to the other element and/or intervening elements can be present, including indirect and/or direct variants. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present.

Although the terms first, second, etc. can be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not necessarily be limited by such terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from various teachings of this disclosure.

Various terminology used herein is for describing particular embodiments and is not intended to be necessarily limiting of this disclosure. As used herein, various singular forms “a,” “an” and “the” are intended to include various plural forms as well, unless a context clearly indicates otherwise. Various terms “comprises,” “includes” and/or “comprising,” “including” when used in this specification, specify a presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence and/or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, a term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of a set of natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances.

FIG. 1 illustrates of an embodiment of a vehicle hosting a manifold according to this disclosure. In particular, a vehicle 100 includes a chassis that supports a manifold 102 in a vehicular heating ventilation air conditioning (HVAC) system, such as a liquid-cooled refrigeration system with an integrated coolant system, as disclosed herein. For example, the vehicle 100 can host an integrated thermal system supported via the manifold 102, whether directly or indirectly. For example, the manifold 102 can be physically coupled, such as via fastening, adhering, mating, interlocking, brazing, molding, or others, to the chassis such that the manifold 102 is supported via the chassis, whether from below the manifold 102, lateral to the manifold 102, or from above the manifold 102.

The vehicle 100 can be a land vehicle, whether manned or unmanned, whether non-autonomous, semi-autonomous, or fully autonomous, such as a car/automobile, a sports utility vehicle (SUV), a van, a minivan, a limousine, a bus, a truck, a trailer, a tank, a tractor, a motorcycle, a heavy equipment vehicle, or others. For example, the vehicle 100 can be a Tesla Corporation Model S (or any other Tesla Corporation model) equipped with Tesla Autopilot (enhanced Autopilot) driver assist functionality and having a Hardware 2 component set (November 2016).

The chassis supports a power source, a drive source, a set of wheels, a computing unit, and other vehicle components. The power source includes a battery, which is rechargeable. The drive source includes an electric motor, whether brushed or brushless. However, an internal combustion engine is possible, in which case the power source includes a fuel tank hosted via the chassis and coupled to the internal combustion engine. The power source is coupled to the drive source such that the drive source is powered thereby. The set of wheels includes at least one wheel, which may include an inflatable tire, which may include a run-flat tire. The set of wheels is driven via the drive source.

The manifold 102 communicates fluids, whether a liquid or a gas, such as refrigerant or a coolant, between two or more components of the vehicle 100. Such communication takes place via a plurality of passages formed inside the manifold 102, where the fluids can be conducted under a high pressure or a low pressure. The passages span between various ports of the manifold 102, where the ports uniquely couple to various fluid sources, such as in a one-to-one manner or others. The manifold 102 can be physically or fluidly coupled to or integrated with a component, including a plurality of components, in any arrangement, whether directly or indirectly, based on an available space and is mostly independent of function. For example, some of such components can include a compressor, a heat exchanger, an electronic expansion valve (EXV) core, a receiver-drier, a refrigerant charge port, a pressure sensor, a temperature sensor, a refrigerant muffler, an internal heat exchanger, or others, as disclosed herein. For example, a set of brazed plate heat exchangers, such as a chiller or a liquid-cooled condenser, can be brazed directly to the manifold 102. For example, the manifold 102 can be physically coupled to a component in various ways, such as brazing, fastening, mating, interlocking, molding, adhering, or others.

The manifold 102 may be made of a same or single material, such as plastic, metal, rubber, or others, or a combination of materials, such as a plastic and a metal or others. The manifold 102 may be formed into a unitary member, such as fused plastic sections, or may be an assembly of pieces, such as a plurality of plates that are stacked and may be physically coupled to each other, including contacting each other, such as via brazing, adhering, fastening, mating, interlocking, mounting, molding, securing, or other ways. For example, the manifold 102 may be constructed via a plurality of flat or planar or formed stamped plates brazed together or a plurality of forged or die cast portions brazed or laser welded together.

The manifold 102 may be physically solid, perforated, opaque, transparent, translucent, or others. The manifold 102 can include any type of material, such as plastic, metal, rubber, wood, or others. The manifold 102 can be of any suitable shape, whether symmetric or asymmetric, whether open or closed. The manifold 102 can define a hole of any shape anywhere therethrough. The manifold 102 can include a projection or a depression of any shape anywhere thereon. Preferably, overall, the manifold 102 is plate-shaped having a thickness dimension between two major surfaces that is less, preferably significantly less, than each of a height dimension and a width dimension of the major surfaces. For example, at least one of the major surfaces can include a portion that can be flat, sinusoidal, arcuate, or others, and that can be polygonally-shaped, whether symmetrically or asymmetrically, such as a rectangle, a square, or others. Preferably, at least a portion of the manifold 102 is plate-shaped. However, note that such structure is not limiting and the manifold 102 can vary, such as being cylindrically-shaped, stair-stepped, or others.

The manifold 102 can be thermally or electrically resistant or conductive or semi-conductive. Although the vehicle 100 contains the manifold 102 in a front portion of the vehicle 100, other configurations are possible, such as where the manifold 102 is positioned in a middle portion of the vehicle 100 or a rear portion of the vehicle 100.

FIGS. 2-5 are various views of an assembly 200, in this case an HVAC assembly, including a plate-shaped manifold 202 embodying principles disclosed herein. The manifold 202 is similar to or the same as the manifold 102, and can include the above-described features and characteristics.

FIG. 2 illustrates an entire assembly 200 with the manifold 202. FIG. 3 illustrates a portion of the assembly 200 in which a compressor 204 is coupled to one side of a the manifold 202 and a condenser 206 is coupled to an opposite side of the manifold 202, as viewed from the compressor side of the manifold. FIG. 4 illustrates the same portion of the assembly 200, but as viewed from the condenser side of the manifold. FIG. 5 illustrates the manifold 202 and a diagram of a fluid routing scheme of the manifold 202 according to this disclosure.

FIGS. 7 and 8 illustrate the assembly 200 from two different viewpoints for ease of understanding how various components can be assembly and hosted on the manifold 202. For example, FIG. 8 illustrates how an evaporator and a TXV valve can also be hosted on the manifold.

In particular, the assembly 200 includes the manifold 202, a compressor 204, a liquid-cooled condenser 206, a coolant container 208, a receiver-drier 210, a plurality of fluid handlers 212, a hose connector block 214, a plurality of hoses 216, a plurality of hoses 218, a thermal expansion valve (TXV) 220, an evaporator 222, a plurality of ports 224, a chiller 226, a plurality of ports 228, a plurality of ports 230, a sensor 232, an EXV motor 234, a port 236, an opening 238, a slot 240, a plurality of high pressure fluid routes, and a plurality of low pressure fluid routes.

The manifold 202 includes a first side and a second side on opposite sides of the manifold. For example, the first side can include a first major surface and the second side can include a second major surface. The first side faces or is exposed to the compressor 204, the ports 224, the sensor 232, the EXV motor 234, and the port 236. The second side faces or is exposed to the liquid-cooled condenser 206, the coolant container 208, the receiver-drier 210, the fluid handlers 212, the hose connector block 214, the hoses 216, the hoses 218, the TXV 220, the evaporator 222, the chiller 226, the ports 228, and the ports 230.

As illustrated best in FIG. 5 , in a region of the manifold 202 that does not include fluid channels, a portion of the manifold 202 removed or not included so as to define an opening 238 therethrough, with the opening 238 extending between the first side and the second side. This enables the manifold to use less material, while still providing a coupling structure, thereby providing an advantage of a lower weight and use of less material. The compressor 204 may face the opening 238, which may include covering the opening 238. The manifold 202 defines the slot 240, which may be used for chassis mounting, such as via mating, interlocking, adhering, brazing, or other ways.

The ports 224 extend from the manifold 202. For example, the ports 224 can be unitary to the manifold 202 or assembled therewith. For example, the ports 224 can be physically coupled to the manifold 202 via brazing, adhering, fastening, mating, interlocking, mounting, molding, securing, or other ways such that the ports 224 can fluidly communicate therewith. The ports 224 are refrigerant charge ports, which may be structured for refrigerant fluid conduction, whether a liquid or a gas. For example, the ports 224 may be threaded and capped when not in use. Note that the ports 224 can be of any shape, size, or type suitable for physical and fluid coupling to the manifold 202.

The sensor 232 senses at least one of a fluid temperature or a fluid pressure or a fluid level or a fluid presence, whether a liquid or a gas. The sensor 232 may be static or active. The sensor 232 may be powered via the power source of the vehicle 100. The sensor 232 may output a signal informative of a value corresponding to a measured fluid property, such as a temperature or a pressure. The sensor 232 extends from the manifold 202. For example, the sensor 232 can be physically coupled to the manifold 202 via brazing, adhering, fastening, mating, interlocking, mounting, molding, securing, or other ways such that the sensor 232 can sense a fluid property. Note that the sensor 232 can be of any shape, size, or type suitable for physical and fluid coupling to the manifold 202.

The receiver-drier 210 is physically and fluidly coupled to the manifold or internal to the manifold 202, whether directly or indirectly, such that the manifold 202 extends between the compressor 204 and the receiver-drier 210. For example, the receiver-drier 210 can be physically coupled to the manifold 202 via brazing, adhering, fastening, mating, interlocking, mounting, molding, securing, or other ways such that the receiver-drier 210 can fluidly communicate through the manifold 202, whether inbound or outbound.

As shown in FIG. 5 , the manifold 202 contains high pressure fluid routes and low pressure fluid routes, which routes are suitable shaped channels or passages with the manifold 202. In particular, the manifold 202 contains a fluid point 242, which is included in the high pressure fluid routes, that enables fluid communication from the compressor 204 to the receiver-drier 210. Moreover, the manifold 202 contains a fluid point 248, which is included in the high pressure fluid routes, that enables fluid communication from the liquid-cooled condenser 206 to the compressor 204.

Furthermore, the sensor 232 is included in the low pressure fluid routes and senses the fluid property from the chiller 226. Note that although various refrigerant passages are shown as formed within the manifold 202, whether high or low pressure, such passages can extend in in the manifold in various ways. For example, exact routing is customizable for different system designs.
